When downsampled to 1080p, you don't need anti-aliasing at all with a 4K resolution, and many people with 4K native displays say the same thing. So that's an immediate boost to your framerate from "max settings".
And the mentality that many PC gamers have, that games have to be played at "max settings" or not at all is stupid. A lot of games are including features that are not intended for use on the current generation of graphics cards, or rendering options which are technically more accurate at a significant performance cost, but visually most people can't even tell it apart.

In Bioshock: Infinite for example, disabling DDoF will give you an extra 20-40% performance depending on the GPU. Contact hardening shadows are another performance hit from ultra settings, but actually look worse in the game due to LoD issues: https://www.youtube.com/watch?v=O-t9OjjVdy8#t=0m44s
Most games have a number of settings which will get you 90% of the visual fidelity at a fraction of the performance cost, as long as you don't mind not playing on "ultra" settings. And many of those "ultra" settings exist because we've been stuck at 1080p for so long with a ton of GPU power to spare.

Sure, rendering 8K isn't enough, now it has to be 8K at 120 FPS
Nevermind that console gamers seem perfectly happy with games running at 30 FPS, which frequently drop below that.

It's 16:9. 5120/2880=1.78

It is said that the Dell monitor is going to cost $2500, and requires two DisplayPort 1.2 connections. The iMac is $2500 and includes a computer.

Ah. Article had a typo then. (5210).

Violence is the last refuge of the incompetent. Unless, of course, it's to keep someone from creating a phone video in portrait mode, in which case it's a pretty good first step. Portrait mooks: KNOCK IT OFF.

Actually to get your timeline, clips bin, effects etc., you really can't run a full scale preview window and get everything in. The preview window, even on a 5K display, will have to be scaled down quite a bit.

If somebody still does not get where is the 5120x2880 coming from, take standard 720p HD which is 1280x720 as everyone knows. Now multiply that by 2 to get 2560x1440 and again multiply this by 2: 5120x2880 magically comes. Starting the same with the 1920x1080 gets to 8K 7680x4320.

By the way, with the 5K there may come time for computer monitors in really wide formats, not only 21:9 but more, with stretching imagination the width can get up to 27:9=3:1 substituting perfectly three monitor systems. Such monitors will naturally have to be curved. Unfortunately manufacturers lack imagination, obsessed with bending TVs.

The confusion came from a typo in the article.
